Pick the gray, also known as climbing ash, picking the gray elegant saying is to gather doe. The doe's elegant name is doe. Poly is the meaning of ****. Said beasts do not have people those in the sexual life of taboos and ethics, there is no social principles of constraints. It is believed that there is incest in beasts. Folk saying that the old man and daughter-in-law have a leg called picking ash. Some people explain that: picking the ashes to bend over the ground on their knees, so that the knees are dirty. Knees daughter-in-law is the same sound, dirty knees, the hidden meaning is dirty daughter-in-law. This is a word describing incest, is specifically referring to incest between the father-in-law and daughter-in-law to have sexual relations. There are many kinds of stories and legends about the origin of the word picking ash, one theory is: the temple burns incense in the furnace, burning more tin foil, over time, formed a large block, the monks pick out to sell money with. Later, the people next to the temple know, also come to the furnace to steal tin. Because of the tin daughter-in-law homophonic, it is derived from the old man stealing daughter-in-law cryptic.　　There are also said to be, folk tinsmith, in the individual do tin pots, clean up the process of sand type, deliberately scrape down some more tin, scraping down the tin is hidden in the ashes of the furnace. Nowadays, people who make gold and silver jewelry also use this kind of tactic to steal the leftovers from customers. This technique is somewhat less impressive than some legitimate craftsmen.　　Folk stonemasons, when making things for people, not completely finished, always leave some tail, and so the buyer to buy back, need to find the village or nearby stonemasons to eliminate this point of residual work. The rules of the countryside, even if it is a little bit of work, at noon to manage a meal, give some money. This is the means by which masons take care of each other.　　Qing people have a "Wuxia Proverbial Union", is another way of saying, as if the source of this rumor: Wang Anshi's son died, he gave his daughter-in-law in the backyard to build another house to live, may be worried about the daughter-in-law out of the wall, often go to monitor the daughter-in-law misunderstanding, the wall inscribed poems, said: the wind flow does not fall into other people's homes. When Wang Anshi saw it, he snapped off the poem with his fingernail. Because it is a lime wall, so it is said to be picking off the lime. In fact, this kind of thing is all just taken for granted. Wuxia Proverbial Union" explains its origin: "Weng private his daughter-in-law, commonly known as picking dust. Little is known about its meaning. According to a temple in the past, incense, tin foil acid burning furnace, ash accumulation day more, panned out of its tin, the city got a lot of money. Temple neighbors know, picking up its ash, theft of its tin as often. Pickpocket ash, steal tin also. Tin and daughter-in-law have the same sound, so I thought it was a cryptic phrase." Another story says, once Wang Anshi walked past his daughter-in-law's room, saw his daughter-in-law sleeping on a bed of transparent gauze, his eyes could not help but glow for it. After all, Wang Anshi was a poet, so he wrote a line on the dusty wall: "A lute in a satin net, I want to play it for the poor." After writing it, he hid to observe his daughter-in-law's movements. Daughter-in-law saw the eunuch sneaking around outside, so out to see what the eunuch wrote on the wall, a see the eunuch left such a phrase, immediately understood what it means, so in the eunuch's verse followed by a sentence: "I would like to borrow the eunuch to play a song, especially to leave the feng shui in my home." Wang Anshi saw his daughter-in-law's words, is secretly happy, I did not expect this time the son appeared, so hurried to use his sleeve to wipe the handwriting on the wall. Son strange, asked his father in what to do, Wang Anshi said, in picking ash. And experts testified that the word "picking dust" is not from Wang Anshi, but from Mr. Su Dongpo, a university scholar, but the storyline is much the same. In folklore, often heard the male and daughter-in-law sexual relations, no matter what the reason is, people in the narrative, often with a proverbial name, called "picking the gray", you must think this is a strange cryptic word it. Of course, it has a history, let me tell you a story to listen to know: in the old days, the daughter-in-law or her husband out of a long time, or because of her husband's untimely death, with a young son inconvenient to remarry, or because of persecution in the father-in-law of the obscene, and father-in-law of the adulterous thing is often the case, the poor people have this situation, and the big family is more.
